Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts detection, in particular to a double-station parking plate edge milling detection tool. Background Art

[0002] The parking of the car is achieved by engaging and disengaging a pawl mounted on the transmission housing and a ratchet mounted on the drive shaft to achieve parking lock and unlock.

[0003] When the car is in P gear, the shift action is transmitted to the parking shift plate, causing it to rotate around the axis of its connecting hole. This rotation of the parking shift plate drives the pawl to engage with the ratchet wheel, thus achieving the parking lock. It can be seen that the parking shift plate is a key component of the car's parking mechanism, ensuring the normal operation of the car's parking system.

[0004] In order to facilitate the use of the parking shift plate with other components, it is usually necessary to mill the end face of the connecting hole of the parking shift plate. Therefore, the parking shift plate needs to be inspected before assembly to determine whether the parking shift plate has been milled to avoid assembly errors that affect the normal operation of the parking system.

[0005] Since the parking shift plate has a special-shaped structure and the milling edge on the parking shift plate has a set angle, the parking shift plate angle cannot be effectively located when inspecting the parking shift plate, and therefore rapid inspection of the milling edge on the parking shift plate cannot be achieved. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] A typical implementation of the present invention is as follows: Figure 1 、 Figure 2 and Figure 4 As shown, a double-station parking plate milling detection tooling includes a support platform 1, a clamping mechanism and an angle positioning mechanism. The support platform 1 is fixed in a suitable position by a support plate 2. The clamping mechanism and the angle positioning mechanism are both fixed on the support platform 1. The clamping mechanism includes a first cylinder 3, which is fixed on the bottom surface of the support platform 1. The telescopic axis of the first cylinder 3 passes through the support platform 1 and extends above the support platform 1. A pressure rod 4 is provided on the top of the telescopic axis, and the telescopic axis is rotatably connected to the middle of the pressure rod 4. A detection platform 5 is also provided on the support platform 1. There are two detection platforms 5. Pressure blocks are fixed on the lower surfaces of both ends of the pressure rod 4. The two detection platforms 5 are respectively arranged directly below the pressure blocks at both ends of the pressure rod 4. A positioning column 6 is provided at the central axis of the detection platform 5. The positioning column 6 is adapted to the axial hole 17 of the parking shift plate 16, so that the positioning column 6 can be inserted into the axial hole 17 of the parking shift plate 16, thereby fixing the position of the parking shift plate 16 during detection.

[0029] When in use, first put the parking shift plate 16 on the positioning column 6, so that the parking shift plate 16 is fixed on the inspection platform 5, start the first cylinder 3, and the telescopic shaft drives the pressure rod 4 to move downward. The pressure blocks at both ends of the pressure rod 4 respectively contact the top surfaces of the two parking shift plates 16, thereby pressing the two parking shift plates 16 onto the two inspection platforms 5 to prevent the parking shift plates 16 from moving.

[0030] A detection rod 7 and a reset buffer rod 8 are also provided on the detection platform 5. The detection rod 7 and the reset buffer rod 8 are symmetrically arranged on both sides of the positioning column 6. The detection rod 7 corresponds to the milling edge 18 at the bottom of the axial hole 17 of the parking shift plate 16, and is used to detect whether the parking shift plate 16 is milled.

[0031] Specifically, such as Figure 3 As shown, the detection rod 7 passes through the detection platform 5 and the support platform 1 and extends to the bottom of the support platform 1. The detection rod 7 is slidably connected to the detection platform 5 and the support platform 1. A micro switch 9 is provided directly below the detection rod 7. The micro switch 9 is a common micro switch on the market. It is fixed on the support platform 1 through a bracket 10. The sensing end of the micro switch 9 is arranged opposite to the bottom end of the detection rod 7. The micro switch 9 is electrically connected to the alarm through a controller. A first spring is provided between the detection rod 7 and the support platform 1. Under normal circumstances, the bottom end of the detection rod 7 is not in contact with the micro switch 9 by the first spring.

[0032] During inspection, the shaft hole 17 of the parking shift plate 16 is sleeved on the positioning column 6, and the first cylinder 3 is used to drive the pressure rod 4 to press the parking shift plate 16. At this time, if the bottom end of the shaft hole 17 of the parking shift plate 16 is not milled on both sides, the bottom end of the shaft hole 17 contacts the top end of the detection rod 7, and the detection rod 7 moves downward, and the bottom end of the detection rod 7 contacts the microswitch 9, triggering the microswitch 9, thereby sounding an alarm through the alarm, indicating that this parking shift plate 16 is not milled. If the bottom end of the shaft hole 17 of the parking shift plate 16 is milled on both sides, the bottom end of the shaft hole 17 will not contact the detection rod 7, and no alarm will be sounded.

[0033] The reset buffer rod 8 is inserted into the buffer hole on the detection table 5, and the reset buffer rod 8 is connected to the bottom of the buffer hole through a second spring. When the parking shift plate 16 is placed, regardless of whether the parking shift plate 16 is milled, the top of the reset buffer rod 8 will contact the parking shift plate 16, thereby buffering the parking shift plate 16 when the parking shift plate 16 is placed. After the detection is completed, the reset buffer rod 8 uses the elastic force of the second spring to lift the parking shift plate 16, thereby resetting the detection rod 7.

[0034] Since the milled edge 18 on the parking shift plate 16 has a specific angle, in order to enable the detection rod 7 to be placed corresponding to the milled edge 18 on the parking shift plate 16 during detection, an angle positioning mechanism is also provided on the support platform 1. There are two angle positioning mechanisms, and the two angle positioning mechanisms are respectively arranged corresponding to the two detection platforms 5, so that the parking shift plate 16 placed on the two detection platforms 5 can be angularly positioned by the two angle positioning mechanisms.

[0035] like Figure 2 As shown, the angle positioning mechanism includes a positioning rod 11, which is located on one side of the test platform 5. When the parking shift plate 16 is placed on the test platform 5, the positioning rod 11 contacts the outer edge surface of the parking shift plate 16, thereby preventing the parking shift plate 16 from rotating around the positioning column 6, and preliminarily limiting the angular position of the parking shift plate 16.

[0036] The angle positioning mechanism also includes a tightening device, which includes a positioning block 12. The positioning block 12 is located on one side of the testing platform 5. A positioning hole is provided in the middle of the positioning block 12, and a push rod 13 is slidably connected in the positioning hole. The tightening device also includes a second cylinder 14. The second cylinder 14 is fixed to one side of the positioning block 12 through a fixing plate 15. The telescopic shaft of the second cylinder 14 is connected to one end of the push rod 13, so that the second cylinder 14 is used to drive the push rod 13 to move. The outer edge surface of the parking shift plate 16 is provided with a U-shaped groove. The shape of the push rod 13 away from the end of the second cylinder 14 is adapted to the outer edge surface of the parking shift plate 16, so that the end of the push rod 13 can be inserted into the U-shaped groove on the outer edge surface of the parking shift plate 16. The second cylinder 14 is used to drive the push rod 13 to move, thereby supporting the outer edge surface of the parking shift plate 16, fixing the angle of the parking shift plate 16, and facilitating detection.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
